A northern goshawk back-propagation artificial neural network (NGO-BPANN) model was established to predict monohydroxycarbazepine (MHD) concentration in patients with epilepsy.
The data were collected from 108 Han Chinese patients with epilepsy on oxcarbazepine monotherapy. The results of 14 genotype variates were selected as the input layer in the first BPANN model, and the variables that had a more significant impact on the plasma concentration of MHD were retained. With demographic characteristics and clinical laboratory test results, the genotypes of SCN1A rs2298771 and SCN2A rs17183814 were used to construct the BPANN model. The BPANN model was comprehensively validated and used to predict the MHD plasma concentration of five patients with epilepsy in our hospital.
The model demonstrated favorable fitness metrics, including a mean squared error of 0.00662, a gradient magnitude of 0.00753, an absence of validation tests amounting to zero, and a correlation coefficient of 0.980. Sex, BMI, and the genotype SCN1A rs2298771 were ranked highest by the absolute mean impact value (MIV), which is primarily associated with the concentration of MHD. The test group exhibited a range of - 20.84% to 31.03% bias between the predicted and measured values, with a correlation coefficient of 0.941 between the two. With BPANN, the MHD nadir concentration could be predicted precisely.
The NGO-BPANN model exhibits exceptional predictive capability and can be a practical instrument for forecasting MHD concentration in patients with epilepsy.
建立了北方游隼反向传播人工神经网络(NGO-BPANN)模型,以预测癫痫患者的单羟基卡马西平(MHD)浓度。
从 108 名汉族患者的奥卡西平单药治疗中收集数据。结果选择了 14 个基因型变量作为第一个 BPANN 模型的输入层,并保留了对 MHD 血浆浓度有更显著影响的变量。利用人口统计学特征和临床实验室检测结果,构建了 SCN1A rs2298771 和 SCN2A rs17183814 基因型的 BPANN 模型。综合验证了 BPANN 模型,并用于预测我院 5 例癫痫患者的 MHD 血浆浓度。
该模型表现出良好的拟合指标,包括均方误差为 0.00662,梯度幅度为 0.00753,验证测试量为零,相关系数为 0.980。性别、BMI 和 SCN1A rs2298771 基因型的绝对平均影响值(MIV)最高,主要与 MHD 浓度有关。试验组预测值与实测值之间的偏差范围为-20.84%至 31.03%,相关系数为 0.941。通过 BPANN 可以精确预测 MHD 的谷浓度。
NGO-BPANN 模型具有出色的预测能力,可以作为预测癫痫患者 MHD 浓度的实用工具。
